| | DICHLOFENTHION Usage And Synthesis |
| Description | Dichlofenthion is an organophosphate insecticide. It was previously used to control nematodes and cutworms mainly on ornamental crops, lawns and turf. It has a low aqueous solubility, is quite volatile and mobile in soil. Dichlofenthion is moderately toxic to mammals, a skin, eye and respiratory tract irritant and a sensitiser. It is highly toxic to fish and aquatic invertebrates. | | Chemical Properties | Colorless liquid. Boiling point 164-169°C (1.33×10-2 kPa), relative density 1.320 (20/4°C). Easily soluble in most organic solvents and kerosene, with a solubility of 0.245 ppm in water. | | Uses | Nematocide, insecticide. | | Definition | ChEBI: Dichlofenthion is an organic thiophosphate. | | Production Methods | Dichlofenthion is commercially synthesised through a multi-step process involving the formation of its phosphorothioate ester structure. The production typically begins with the reaction of 2,4-dichlorophenol with diethyl phosphorochloridothioate, forming the active compound. This reaction is carried out under controlled conditions using an organic solvent and a base to neutralise the hydrochloric acid byproduct. | | Mechanism of action | Acetylcholinesterase (AchE) inhibitor | | Safety Profile | Poison by ingestion and
skin contact. A very toxic insecticide.
